Is my wrist broken do i need physical therapy?

So before i hurt my wrist. I hit the ball wrong in vollyball. There was bruising and some swelling. So after the pain got so bad i went to the doctor, it was NOT broken so i went home with just a brace. BUt it kept hurting. It has been two weeks since i took the brace off. Now i still can not move it all the way back or down and every once in a while it feels like i have a bad writ cramp wats wrongz?
